TECHNICAL DETAILS| AVRO TUDOR
The Tudor’s circular fuselage was a conventional, all-metal semi-monocoque structure of 10ft (3m) diameter, formed from channel-section frames with stringers bolted directly to them. The outer sheeting was of two layers of light aluminium sandwiching kapok insulation material.
The fuselage structure comprised four elements joined by T-section extruded frames. Where the wing spars met the fuselage, the frames were of deeper section with plate webs to which L-section extruded booms were riveted. The fuselage floor was of light alloy and mounted on a framework of light channel members supported by vertical posts attached to the part of the frames. Wing-tofuselage attachment was achieved via cast shrouds bolted to the spars and riveted to the skin. At the centre section-fuselage junction only the spars pierced the skin.
Based on the Lancaster, the wings comprised five-piece, all-metal, twin-spar structures and were of modified NACA 23000 section at the roots. The centre-section spar webs parted at the fuselage skin line, where a separate length of web was carried across the fuselage interior on continuous booms.
The centre section terminated immediately outboard of the inboard…
